Abstract (en)

[origin: EP0776006A2] A magnetic recording and reproducing device according to the present invention operates with the steps of moving a magnetic tape having having a plurality of tracks per frame and a plurality of CTL signals recorded thereon, keeping count of the pulses of an FG signal corresponding to the rotation of a capstan motor by FG counting means, resetting the count of the FG pulses by the CTL signal reproduced by a fixed magnetic head, detecting the track number by the CTL counting means reset by a frame reference signal, controlling, at the start, the start timing on the basis of the tape stop position detected by the FG pulse counting means and CTL counting means and the reference frame signal from the reference frame signal generating means, said device preventing the thinning of tracks at the editing point in after-break recording and the disturbance of images immediately after the start, not requiring a special circuit or complicated software-wise processing, providing a stabilized slow-reproduced image. Further, in a magnetic recording and reproducing device for intermittent recording, there is no danger of causing thinning to recorded tracks; a reproduced image of high quality can be obtained. <IMAGE>
